High-Speed Printing of Transistors: From Inks to Devices

摘要: The realization of a high-speed printing technique with high resolution and pattern fidelity is critical to making printed electronics viable technology for manufacturing. requirements are substantially different that those graphic arts. To make reality, it necessary deliver resolution, good reproducibility, excellent fidelity, process throughput, compatibility the requisite semiconductor, dielectric, conductor inks. In this paper, we review physics formation from pixelated primitives, such as exist during inkjet gravure printing, will show how control drop merging drying can be used produce high-fidelity shapes, including lines, squares, intersections. We additionally discuss physical underpinnings these techniques scaled highly patterns, sub-2 micron features at speeds $\sim$ 1 m/s. Finally, in conjunction high-performance materials, describe our fully transistors on plastic, offering high-switching speed, over large areas.
